Abstract (en)

A transfer gate circuit including a first MIS transistor (Q1) which transmits an input signal ( @) supplied from an input side thereof to an output side thereof in accordance with a control signal ( @) supplied to a gate of the first MIS transistor (Q1); an inverter circuit (Q4,Q5) connected between power supply lines which inverts the potential of the input signal; and an output level guarantee circuit comprising second and third MIS transistors (Q2,Q3) which have a conductivity type opposite to that of the first MIS transistor (Q1) and are connected in series between one of the power supply lines (Vcc2) and the output side (V), and an output signal (A) of the inverter circuit (Q4,Q5) being supplied to a gate of the second MIS transistor (Q2), an inverted signal ( phi ) of the control signal ( @) supplied to the gate of the first MIS transistor (Q1) being supplied to a gate of the third MIS transistor (Q3).
